Anyone over 17+ have success stories?

Anyone over 17+ have success stories? I have a breakdown about my stutter every week. It seems like an endless cycle that I’m never going to get out of. Everyone undermines the severity of having a speech impediment. Talking is literally a part of EVERY aspect of our lives. Familial, school, work, and social life. Even my romantic life. I don’t know if I’d want to put my burden onto a romantic partner, or if anyone would even want me with this disability. I want to be a doctor but I can’t. Because I cant speak. I cant do what I truly want to because this stutter is holding me back. I can barely say my own name. I don’t know if I should have kids because kids tend to mimic your speech mannerisms, and I would never wish this disability on anyone. I’m so tired. I’m exhausted. I feel so alone. I’m only 17 and I feel like this is the end. I think I’m too old to fix this now. :( Please please please, if anyone around my age or older has fixed their stutter PLEASE put your success stories below. I really need hope.
